Designed specifically for use on smaller APS-C sensor DSLRs, the new EF-S 24mm is a wide-angle pancake prime featuring Canon’s STM step autofocus motor for smooth video capture. At just $149, it looks like a “no-brainer” for Canon APS-C video shooters, but how does it compare optically against a vast range of other options available? We dissect the DxOMark Lens Metric Scores to find out.

As one of the earlier adopters of the mirrorless design for compact camera bodies, Samsung has amassed a wide range lenses. The stabilized 18-200mm is one of their earlier models but does it have what it takes to compete with rivals? Read on to find out.

Sigma’s 18-250mm f3.5-6.3 DC OS HSM zoom won praise for its balance of performance and convenience, but it looked bulky after rival Tamron introduced the diminutive 18-270mm F/3.5-6.3 Di II VC PZD. Reducing the size, and weight while updating the optical construction to allow a new minimum focus distance of 35cm, the 18-250mm F3.5-6.3 DC MACRO OS HSM is Sigma’s response. But has the redesign compromised the optical performance, or is it a valuable addition to the range? Read on to discover our verdict.

Sigma announced its 18-200 mm f/3.5-6.3 DC OS HSM II lens at the beginning of October 2011.
